Patented Nov. 12, 1929 ARLYN T. .VANQE, or LOS AnGELEs; CALIFORNIA r zYsIoIANs nILA'ron loator to be used in dilating parts of the human In the treatment of manydiseases it is the and particularlyslight pressure'upon them. For example, in the treatment catarrh, it is an approved practice among to insert the little fingerinto the nostril and exert slight pressure upon the 'turbinates to effect the draining of-lymph.

It is also the practice to treat patients forcolds in the headin a similar manner.

The general object ofthis invention is to for such a purpose and which will operate to exert gentle pressure against the walls or membranes of the part into which the dilator isinserted. r 1 'Inthe use of sucha dilator, it frequently "happens that the part treated at a considerable distance from the opening into it. In order to meet thisdifliculty, one of the objects of the invention is to provide a construction for the dilator which will enable the principal dilating elfect to bejlocjated near "the inner end or extremity of the inserted dilator.

I provide' a and near the outer endof this stemjIlattach a dilator body or bag 2 which is also preferprovided with: af75 flexible wall 3 of rubber or similar material- If desired, the wall 3 maybe madeintegral with a heade of-fsoft rubber in which is embedded anchors or hooks 5 formedon the ends of 'the'tubular stem. This head 4 should 7 be of soft rubber so that it cannot, injure parts against which ,itis pushed. The other end of the dilator body is secured on the stem by an airtight connection which in the present instance includes two collars 6, between'ss whichthe end wall of head? of the dilator;

body isheld. Theelasticity of the rubber will be 'sufiicient to make" this an airtight connection. '4

In order to cause the principal dilationto'eo occur near the head or nose 4- of the instrument, I-preferto'makethe wall 3 of graduated thickness,'its thinnest portion being disposed near the head l. With this arrange- I fluid suchas air is forced; into .95 the interior of the body 2, the wall 3- will tend to assume approximatelythepositionindicatedby the dotted line 3 1 r In order tosupply fluid, such as air under pressure, to the 1nter1or of the body, I pro- T OFFICE body, when the pressure of the air within it zislexerted,"the wall Will project itself in the iiorm of protub'erances or lobes 24 which will vide an air bulb 8, such as employed on atomizers. This bulb is of a common type with a check valve, not illustrated, located at the point 9, and the neck of this bulb is secured to a metal sleeve 11. In F ig. 1, 12 indicates a bore through this sleeve. When the bulb 8 is collapsed by pressure in ones hand, the check valve at 9 prevents the escape of air and this air then passes under pressure up through the stem 1 to a point nearthe 'head 4, at which point it passes through orifices 13 which open communication betweenthe bore of the stem and the interior of the dilator body2.

,7 orderto provide means for releasing the air at will, I provide a smallneedle valve 14 having a knurled head, and the pointv 15 of f a this needle valve seats in a small opening in the side-of thestem. In

small groove The stem 1, V bent, as indicated at the bend 17 (see Fig. 1), and at the Outer end ofthe stem a small cross baror handle 18 maybe provided to facilia greatly facilitates the use of the instrument.

In Fig. 4, I illustratesthe manner in which tateholding and operating the instrument. Adjacent this handle18, a grooved neck 19' is provided, overwhich-the end of-a rubber tube 20. may be forced, and a similar grooved neck 21 may be provided'on the end. of the sleeve 11 to enable the other .end of the tube to be secured to it; This tlexible tube 20 the dilator is' employed in a treatment for I nasal catarrh or other condition whichhas affected r the turbinates.

. headyt of the instrument isindicated, located in t-lrerightnaris 22, and septumf23 and exerting pressure between'the "septum,th-'e middle and the inferior turbinate bodies. The turbinate bodies at the lettare represented of normal size as though the lymph in them h'adbeen 10f this instrument.

.It will be noted that on account-of the flexible character of the wall'ot the dilator extend themselves into the canalsar'ound the turbinates, and in this wayipressure will be exerted'by the instrument over'a considerable area of theturbinatebodyn In using the instrument, thepressure'can be exerted for any desired length of time and then relieved by 'nnscrewin'g'the needle valve 14., i

While I consider that this instrument will have great utility for the purpose described above, I do not limit myseltin any way to its use for this particular purpose, and I intend that it shall be used at any-point on other words, the valve has a threadedshank 16 likea screw, and in the side of this screw is a which enables. thebore 11? to communicate with the atmosphere when this needle valve i 7 is open.
